Abstract:
A sensitive method for the determination of inorganic mercury and total organomercury in chemical waste water by cold vapor generation-atomic fluorescence spectrometry (CVG-AFS) was proposed. Inorganic mercury was directly determined by CVG-AFS. Organomercury was oxidized by potassium persulfate to its inorganic form prior to analysis. The difference between the two data was the value of total organomercury. Parameters affecting the sensitity in the process for the determination of mercury had been studied and optimized. Detection limit of mercury chloride was 8.2 ng/L.
